In ExtremeTech’s latest This is My Rig build, we run through Rich Ackermann’s liquid-cooled hexa-core workstation. This 75-pound monster runs 64GB of RAM, dual 120mm radiators, over 6TB of storage, and still looks better than any computer you’ve ever built.

Those dastardly devils at iFixit have managed to get their mitts on one of Valve’s 300 Steam Machine prototypes and, of course, torn it down. Inside is a quad-core Haswell Core i5-4570, a Zotac GTX 780 graphics card, 16GB of Crucial Ballistix Sport (PC3 12800) RAM, and a 1TB 5400 RPM Seagate hard drive. If you wanted to build your own SteamOS-powered doppelganger, it would set you back around $1300 to match Valve’s Steam Machine part-for-part.
